White Mold Development: Is your soybean field at risk?

According to USDA-NASS crop progress report for the week of July 17, 49% of the soybeans in South Dakota are at flowering. The flowering growth stage is also the time when white mold infection is initiated. The white mold pathogen infects the soybeans through the flowers that are senescing after pollination.

Wheat Stem Maggots Observed in S.D. Wheat

While scouting wheat fields throughout South Dakota, we have started noticing the presence of bleached heads scattered throughout many different fields. These discolored heads are the result of an infestation of the wheat stem maggot.

First Soybean Aphid Populations Detected in South Dakota

While scouting fields this week, we observed winged (alate) soybean aphids in Southeast South Dakota.

Barley yellow dwarf developing in winter wheat.

Barley yellow dwarf is starting to develop in winter wheat. Barley yellow dwarf is caused by the Barley yellow dwarf virus (BYDV). This disease usually becomes more distinct at flag leaf emergence. A typical symptom of Barley yellow dwarf is the purplish-yellow color of infected leaves, especially the flag leaf.

Which mite is it? Identifying the mites in wheat fields

In South Dakota, the most commonly encountered mites in wheat are wheat curl mite and brown wheat mite. In addition to feeding, wheat curl mites are vectors of Wheat streak mosaic virus. Brown wheat mites can build up large populations and injure wheat through feeding. There are other species of mites that may also be observed in wheat, but generally do not reach populations large enough to cause significant injury.
